What remained were the five halberd techniques and his death summon technique. He didn't read through them in-depth like he did at the other techniques.
After he finished forming them, he said to the system:
"Give me the picture and directions of my death summon technique."
'It's in your mind now, master.'
Ibro felt the appearance of the image with many rows of words. He started to study all this info regarding this technique. It was worthy of a high-end technique.
It had two modes of upgrades, one to raise the quantity and the other was to raise the quality. The amount needed to raise the quality was really big. He needed 20k souls to raise it to the second grade only.
By this amount of souls, he could raise the quantity by three grades at least. Ibro didn't care about the quantity, for now, what he needed was to raise the quality.
